Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
We advance theoretically and verify experimentally a protocol for generating arrays of self-similar light beams with the aid of almost periodic structures (APSs), which we refer to as pure amplitude 2N-gonal APSs. We illustrate our general results by realizing a circular array of exact replicas of a Laguerre-Gaussian source beam and registering good agreement between the theory and experiment. Our work carries promise for optical communications, optical tweezing, multi-particle trapping, screening, and micro-manipulation.
